## Notes

- PH is the 2.0 mm pitch wire-to-board connector on small LiPo packs and boards (housing PHR-nn, headers B..B-PH-K / S..B-PH-K). Pitch span of n circuits = 2.0 × (n − 1) mm.
- The sheet's per-circuit width columns are scrambled in the text layer, so the housing width formula is not published here (a reading of 2n + 1.8 mm was not confirmed). Dimensions of the header and housing drawings are likewise unlabeled in text. No file: the datasheet drawing prints its dimensions as bare numbers without naming the feature each one measures, so no outline or cutout is drawn from them.
- Existing KiCad-derived PH / XH / EH / GH header bounding boxes are on the JST connectors page.
